This project will deliver a fibre optic cable at Bolnely 400kV substation which will be routed around part of the perimeter fence and in the near vicinity of at least one 400/132kV SGT, a 13kV tertiary reactor, a 400kV air blast circuit breaker and other switchgear.
This fibre will be lit using a sensor which has been developed by BT which uses the fibre to detect audible sounds. The data from this will be sent across an internet connection back to a BT server to analyse the noise signatures on site.
